A variation of the ricer flyby whereby a driver of a vehicle attempts to initiate a race by cutting off the target at a high rate of speed but before the driver of the other vehicle can respond or realizes what just happened while they were minding their own business, the ricer proceeds to turn off onto a side street, parking lot or pull a u-turn.

The technique is usually performed to save face by avoiding embarrassment and keep the ego of the driver and their inadequate machine intact. This serves to boost the self-esteem of the instigator or for the purpose of ultimate internet forum bragging rights.

Historically this maneuver was performed by drivers of anemically underpowered cars but the popularity of ricer turn offs has increased exponentially and can be seen now being performed by vehicles of every make and model including imports, domestics, minivans, pickup trucks, luxury vehicles and mopeds.

When a news outlet or government agency posts obvious falsehoods or manufactures fake consensus, the comments are turned off.

Version 1: An offer from another person that you previously found attractive (sometimes in the heat of the moment) which completely changed your mind so that you are now repulsed by them.

Version 2: The strategy of blowing people off at places such as bars by facetiously leading them to believe that you are interested in them and then making an outrageous offer meant to turn them off and make them go away.

same thing as getting your “snot box rocked” or getting your “curtains closed“
